Diesel mechanic training in Tennessee

14 diesel mechanic programs with costs, results and funding that can make them free

13 schools offer these diesel mechanic programs, and Tennessee has approved every one for workforce funding. Each shows its price if you pay yourself and how past students did.

Diesel mechanics inspect and repair buses and trucks and maintain diesel engines of every kind. Community colleges and technical schools offer certificates and degrees in diesel repair, employers may require or prefer certification, and some jobs need a commercial driver's license to test-drive trucks and buses.1 Under federal rules, anyone paid to handle the refrigerant in a truck's cab air conditioning must be certified by an EPA-approved program.2

In Tennessee, 8 of the 14 programs take students without a high school diploma and 6 ask for a diploma or equivalent.

By kind, the 14 programs here are heavy equipment mechanic (10 programs) and diesel technician certificate or diploma (4 programs).

How to pay for diesel mechanic training in Tennessee

WIOA funding can pay for diesel mechanic training in Tennessee

Every program on this page is approved for it. Whether you qualify, how much your local area pays and how to apply are on our page Does WIOA pay for job training?

Financial aid and grants for diesel mechanic training

Most students can get federal student aid for college, career school or trade school. A Federal Pell Grant, unlike a loan, usually doesn't have to be repaid. Ask the school whether its program qualifies.78

GI Bill for diesel mechanic training

Veterans, service members and qualified dependents can use GI Bill benefits for non-college training programs.9

The program list does not show which programs accept these. Ask the school.

Where the Tennessee diesel mechanic program numbers come from

Which Tennessee diesel mechanic programs are on this list?

These are the diesel mechanic programs Tennessee approved for WIOA funding (public workforce funding under the Workforce Innovation and Opportunity Act), as reported to the US Department of Labor for program year 2024 (July 2024 to June 2025). Each state keeps its approved programs on an eligible training provider list (ETPL).10 The list here covers programs approved as of June 30, 2025. Schools that never applied for approval are missing, so this is a part of what Tennessee offers.

How the prices and results of Tennessee diesel mechanic programs are measured

Prices are tuition and required fees for someone paying without workforce funding, as the school reported them; check the current price with the school. Results describe students who left each program in recent years, so they are no guarantee, and the yearly earnings are the reported quarter times four, an estimate. A program without a "Trained with WIOA funding" line may still take WIOA students. Where a field was left empty or withheld, the page says "Not reported", and "Left out" where a figure was filed but failed one of our checks; nothing is estimated to fill a gap. Where the numbers come from explains each figure in full.
